PAPER-MAKING lVIACHINE.

SPECIFICATION forming part of Letters Patent No. 459,351, dated September 8, 1891. Application filed March 14, 1891. Serial'No. 385,036. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS M. VAN WOR- MER, a citizen of the United States, residing at Sandy Hill, county of Washington,and State of New York, have invented certain new and useful Improvements in Paper-Making Machines, of which the following is a specification.

My invention relates to such improvements;

and it consists of the novel construction and combination of parts hereinafter described;

parts in the vertical longitudinal section of a movable frame for supporting the breast-roll when detached from the vibratory frame, showing a portion ofv the shake-posts in elevation and of a like frame to receive the rollwhen removed from the machine, located outside of the vibratory frame.

Referring to Fig. 1 of the drawings, A A are the shake-posts which support the breast-roll A. The endless wire belt A passes around the breast-roll and over the small rolls A to the usual couch-rolls. (Not shown.) The small rolls A are supported by frame A pendent from the shake-rail A.

As such machines have been heretofore constructed the breast-roll bearings, when secured to the shake-posts, were located on their front side, so that the posts came between the breast-roll and the couch-rolls, and to introduce a new wire web or belt or to remove the old one from the rolls for repairs or for any other purpose it was necessary to remove the dekle-frame A which is very heavy and difficult of adjustment, and to lift the breastroll from its bearings upward and rearward to the position occupied by the dekle-frame to give the wirethe slack necessary to remove and insert the roll. The wire belt is frequently,if not generally, from nine to ten feet wide,while the distance from the breastroll to the couch-rolls is about twenty feet, and very little lateral movement can be given to so wide a belt obliquely to its line of travel between such rolls. Consequently one of the supporting-rolls must be withdrawn from the line of the belt and inserted within the belt endwise from one side of the belt. Usually the belt is folded or rolled up and a fold slipped on over a couch-roll. Then the dekleframe and small rolls are removed the belt straightened out toward the breast-roll, the latter roll lifted from its bearings and inserted within the belt and then returned to its bearings. It was necessary to remove the dekle-frame because the bearings of the breast-roll, being located on the front side of the shake-posts and its journals projecting out beyond such posts the roll could not be moved toward the couch-rolls to get the necessary slack in the belt without lifting the roll up over the posts into the place occupied by a portion of the dekleframe. The journals of the breast-r0ll are made long to project beyond their bearingboxes to provide means for lifting the roll from its bearings, long pipes or tubes being slipped on over the journals by which the roll 4 is lifted. I have ascertained that by locating the breast-roll on the back side of'the shakeposts, which is the side facing the couch-rolls, I am able to lift the breast-roll from its bearings and move it toward the couch-rolls to slacken the wire belt without disturbing the dekle-frame or any of the parts above the shake-rails. The journals B of the breastroll are supported by bearing-boxes B, resting upon the brackets B The boxes are detachably secured to the brackets by bolts B passing through lugs B one on the box and one on the bracket. The brackets are vertically adjustable upon the shake-posts, being secured thereto by a nut and bolt B in the slot B and resting upon the adj usting-screw B rotary in the screw-threaded lug B A frame 0 is erected from the floor on each side of the machine substantially in line with the shake-posts, each frame comprising a pair of uprights C and a fixed connecting crossbar 0 near the floor. The uprights are adapt- ICC ed to support on their upper ends the detachable cross-bar O The fixed cross-bars O are adapted to support a detachable rollsupporting frame C This frame is provided with a series of concaved rolls 0 each having trunnions 0, provided with bearings 10- cated in the frame 0 The frames C are preferably permanently located in the position shown, being secured to the floor by bolts; but when desired the bolts may be removed and the frames detached from the machine.

To remove the breast-roll from within the wire belt, the rolls A supported by the shakerail frame A, are first removed and the journal-boxes detached from the brackets by removing bolts B The roll is then lifted one end at a time and the boxes removed from the brackets, which allows the journals to be lowered upon the brackets. The roll is then rolled back until the journals rest upon the detachable cross-bars C Sufficient slack is thus given the wire belt, as shown by thei dotted lines in Fig. 1, to permit the rollframe 0 and rolls to be placed on the fixed cross-bars 0 between the wire and the'breast- 4 roll in the position shown in Figs. 1 and 2. The detachable cross-bars are then removed and the rolllowered upon the rolls 0, as shown in Fig. 2, after which the breast-roll is drawn out upon the portable roll-frame C having.

the rolls C as indicated by dotted lines in 1 Fig. 2. The rolls 0 and frame 0 are then removed from the fixed cross-bars 0 leaving the wire belt free to be rolled up and taken journal-boxes in place beneath the journals, and thenreplacing the rolls 'supported'by the shake-rail frame. I am thus able to easily and quickly substitute a new for an old wire belt without the delay and labor incident upon removing and readjusting the dekle-frame and connecting parts, which require very careful adjustment.

In small machines or with a sufficient number of attendants the breast-roll can be removed from or inserted in the slackened wire belt by lifting the same in and out; but I prefer to make use of a detachable track or way,

as the frame 0 and rolls Ciinserted between the breast-roll and wire belt, upon which the roll can be moved out of and into the belt, substantially as hereinbefore described.

The portable way consisting of frame 0 and rolls 0 affords a convenient support for the breast-roll after the same is withdrawn from the belt; but any form of support may be provided, or the roll may be supported by attendants while the belt is changed.

What I claim as new, and desireto secure by Letters Patent, is

1. In a Fourdrinier paper-making machine, the combination, with the wire-supporting breast-roll and roll-journals, of a pair of shake- .posts and roll-supporting journal-boxes detachably secured to such posts on their rear side, whereby the breast-roll can be detached from the shake posts and moved rearwardly for the purpose of giving slack to the wire belt, substantially as described.

2. In a Fourdrinier paper-making machine, the combination, with the wire-supporting breast-roll and roll-journals, of a pair of shakeposts, roll-supporting journal-boxes detachably secured to such posts on their rear side, a detachable way for such roll, and a pair of Way-supports located in the rear of the shakeposts, substantially as described.

In testimony whereof I have hereunto set my hand this 7th day of March, 1891.
